Letters Patent No. 99,152, dated Jmmwry 25, 1870.

The Schedule referred to in these Letters Patent and making part of the same.

To whom 'it may concern Be it known that I, W. H. BURNS, of Grafton, county of Worcester, Commonwealth of Massachusetts, have invented a 'new and improved Shuttle- Spindle Spring; and I do hereby declare that the following is a full and exact description thereof, reference being had to 'the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

This invention consists in the arrangement of a spring, constructed as shown, with the heel of the spindle, for the purpose of holding the cop orA bobbin spindle of the shuttle in its elevated charging and doiiing position, or depressed and working position, hereinafter more fully described. i

In the accompanying drawings- Figure l represents a sectional view of the shuttle,-

with the spring applied to the heel of the spindle in itsdepressed and elevated position, (the dotted lines when elevated.) Y

Figure 2 represents the coiled lever-spring D, one end coiled, the other straight.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The spindle of the shuttle is hinged at its heel on pintle a.

, A step is made in the heel of the spindle, as seen at b, to receive the straight end of the spring.

The coiled lever-spring D, as seen in fig. 2, is formed with one end straight and the other coiled.

The straight end is marked c. The coiled end is placed on pin d. This pin passes through the shuttle and holds the spring inits position.

The straight end of the spring is placed in the step of the heel, so that as the spindle is elevated the spring is forced back on the coil, until the end in the step passes the line of the pintle a in the heel.

Stopper e arrests the spindle at a desired elevation, and the spring, pressing against the heel, keeps it in this convenient position for charging and dofiing.

As the spindle is returned to its working position, the spring is again forced back on the coil until the end c passes the line of the pintle, when the spindle is arrested bythe stopper e, and the end of the spring, pressing against the heel in the step b, keeps it in its working position.

What 1 claim as my invention, and desire to secure by Letters Patent, is f The coiled lever-spring d, constructed as described, and arranged with the heel of the spindle, as and for the purposes herein specied.

- W. H. BURNS.
